31. Write the rations for Sin C, cos C, and tan c.
### Question 31/36

#### Write the ratios for \(\sin C\), \(\cos C\) and \(\tan C\).

A right-angled triangle \( \triangle ABC \) is shown with:
- The length of side \( AB \) = 7
- The length of side \( BC \) = 24
- The length of the hypotenuse \( AC \) = 25

```
      A
      |
      |\
  7   | \  25
      |  \
      |   \
      |_____\ C
      B      24
```

*Note: Use slash (/) to separate the numerator and denominator.*

- **\(\sin C\)** (Sine of angle \(C\)) = Opposite / Hypotenuse
- **\(\cos C\)** (Cosine of angle \(C\)) = Adjacent / Hypotenuse
- **\(\tan C\)** (Tangent of angle \(C\)) = Opposite / Adjacent

| Term  | Ratio         |
|-------|---------------|
| \(\sin C\) | [__________] |
| \(\cos C\) | [__________] |
| \(\tan C\) | [__________] |

#### Explanation:

1. **\(\sin C\)**: This is the ratio of the length of the side opposite angle \( C \) to the hypotenuse. Here, the opposite side to angle \( C \) is \( AB \), and the hypotenuse is \( AC \).

2. **\(\cos C\)**: This is the ratio of the length of the side adjacent to angle \( C \) to the hypotenuse. Here, the adjacent side to angle \( C \) is \( BC \), and the hypotenuse is \( AC \).

3. **\(\tan C\)**: This is the ratio of the length of the side opposite angle \( C \) to the side adjacent to angle \( C \). Here, the opposite side to angle \( C \) is \( AB \), and the adjacent side to angle \( C \) is \( BC \).

Fill in the provided boxes with the appropriate ratios to complete this exercise.
